8 Claims. (Cl. 21934) This invention relates to baseboard panel heatersfor recessed or surface mounting on a wall and relates more particularlyto glass panel heaters in which a basic heating unit is adaptable to anyform of baseboard panel having a common type of unit mounting and wireterminal boX.

The invention consists essentially in the provision of either a recessedor surface mounting wall panel both having the same form of heatingpanel mounting and wire shielding box and a basic panel heatercompletely wired, the basic panel heater being provided with endcompartments, enclosed by removable front covers, within which thenecessary wiring connections can be'made between the heating element andthe house wiring after the assembled heater has been mounted in place onthe wall,

The object of the invention is to provide a baseboard panel heater whichcan be used as a surface mounted heater Where no provision has been madein the Wall to recess such heaters, or can be fitted into ready preparedrecesses in the wall by the simple provision of exchanging one type ofwall panel for another.

A further object of the invention is to provide a baseboard panel heaterin which a basic heating unit is completely wired and has wiring leadsbrought into a separate end Wiring compartment where the leads can beconnected to the house wiring without disturbing the heating elementitself or its housing and guards.

A further object of the invention is to provide a baseboard panel heaterin which the heating element can be removed from its housing and bereplaced without disturbing the baseboard panel as a whole.

These and other objects will be apparent from thefollowing detailedspecification and the drawings forming a part thereof, in which- Fig. 1is a vertical elevational front view of a baseboard heating paneladapted for surface mounting on a wall.

ts atent 2,849,586 Patented Aug. 26, 1958 Referring to the drawings, thebaseboard panel heater 5 is composed of two main portions, the Wallpanel 6 and the basic heating unit 7.

The basic heating unit 7 is in the form of a shallow rectangular tray ofsuitable dimensions considering the locations in which the heaters areto be fitted and the voltage of the supply. The tray is formed of sheetmetal and has a base sheet 8 extending the full length of the unit andis turned up at the ends to form the endwall-s 9 and at the sides toform the side walls 10. The side walls 16 are inturned along their topedges to form theflanges 11. Z-shaped members 12 extend across the trayto form end compartments 13 within which the wiring connections betweenthe supply and the heater are'jo-ined. The glass panel heating element14 is mounted in suita'ble spacers 14a within the centre compartment 15of the tray and is held in place by the corner brackets 16. End coverplates 17 are secured to the flanges 18 of the tray by means of thescrews 19. A bushing 20 is fitted in the base sheet 8 in one of the endcompartments 13 through which the supply wires 21 are brought into thecompartment 13, while a bushing 22 is fitted through the adjacentZ-shaped member 12 to carry the terminal wires 23 from the glass panelheating element 14 into the com' partment 13, where they can be suitablyjoined with the supply 'wires 21.

A wire guard 24 generally covers the area of the glass panel heatingelement 14 and the centre compartment 15 and is secured to the flanges11 by the screws 25. The wire guard 24 serves to hold down the cornerbrackets 16 but is clear of the end cover plates 17 to enable thesecover plates 17 to be removed to expose the connections of the wires 21and 23 without disturbing any other part of the heater assembly.

The wall panel 6 shown in Figs. 1, 2, 6 and-7 is suitable for surfacemounting on a wall and is here shown as being in the form of a pictureframe although it could be in any other form to give a degree ofprotection around the edges of the basic heating unit 7. The base sheet26 of the panel 6 isformed with outwardly sloping side wall 27 inturnedat 28, to give a smooth finish around the edges of the panel. Brackets29'a1'e secured to the base sheet 26 at the corners where the base sheetjoins with the sloping walls 27 and have secured to them The threadedscrews 31 passbasic heating unit 7 as required. The brackets 29 and 33space the basic heating unit 7 away from the wall panel 6 to provide anair circulating space 6:: therebetween to provide a more eflicient aircirculation than is normally available in baseboard panel heaters. Awire shielding box 34 is provided in the base of the panel 6 into whichthe supply wires 21 from the wall box 21a are led through the aperture35 from a wall outlet. This wire shielding box 34 is located in linewith the bushing 20 in the end compartment 13 of the basic heating unit7. The Wire shielding box 34 is approximately the same height above. thebase sheet 26 as is the top surface of the brackets 29 and 33 and servesto isolate the wires 21 in the open space between the heating unit 7 andthe base sheet '26.

In Fig. 8 the same arrangement of support brackets 29 and 33 and wireshielding box 34 is shown as in Fig. 5

but the panel 36 is for mounting on a recessed wall as shown in Fig. 3.The panel 36 is dishedwith straight side walls 37 projecting out fromthe base sheet 38 to support the wall flanges 39.

When it is desired to mount a panel as above described on a wall, thefront cover plate 17 covering the end compartment 13 immediately overthe wire shielding box 34,

intermediate support brackets 33 are provided at suitable intervals togive added support to the Suitable insulating spacers 4t) are fitted onthe base sheet 8 to insulate that sheet from the heater element 14 as ashort circuit protection should the base sheet 8 be dented or becomewarped in usage. A current limiting thermostat 41 may be fitted asrequired.
